Improvement in steam-engine lubricators



UNITED STATES '.l. G. PELTON, OF LYONS, IOWA.

IMPROVEMENT IN STEAM-ENGINE LUBRICATORS.

Specification forming part of Letters Patent No. 67,577. dated August 6,1867.

.be adapted; and I do declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings,

making a part of this specification, in which- Figure l is a perspective view, and Fig. 2 is a perpendicular cross-section, and Fig. 3 a horizontal cross-section at A, of said oil-cup.

B represents the reservoir of cup, to be made of any suitable material. C and D represent spiral springs, to hold the valves E and F to their seats, except when being operated. G represents the piston, and H the handle, of a pump, connected with the oil-cup between the valves E and F and I represents the opening for the ingress ofthe oil to the steam-chest of engine.

The valves E and F are so located and constructed, with reference to each other, that by suficiently depressing the upper valve E its lower part can be brought in contact, and depress the lower valve F, at the same time opening both valves, so as to permit the passage of steam through the entire length of the oilcup, for the purpose of cleaning and removing all dirt or adhesive substance that may accumulate in any part of the cup or pump.

To operate the machine, withdraw the piston of the pump, as indicated by the red lines. By the vacuum being formed within the barrel of the pump, the pressure of the atmosphere upon the oil in the cup forces down the upper valve E, as indicated by the red lines, and permits the oil in the cup to descend into the barrel of the pump; then force back the piston of the pump to its original position, and the upper valve E is first closed, and the lower valve F is opened, and the oil is forced down the opening I into the steam-chest, or other locality where needed, all of which is effectively and instantaneously done Without waste of steam or wear of parts.

What I claim as my invention, and desire to secure by Letters Patent, is

The eolnbination and arrangement of the valves E and F and springs C and D, in connection with the pump, arranged to operate substantially as above stated, and for the purposes therein set forth.
